运行效率和功率因素都有较大的，采用双功率电动机缺点在于:如果不能解决系统的配合问题，则起不到节能作用，②增加蓄能器，蓄能器用来增加抽油机的转动惯量，充分发挥其动能的均衡作用，降低电动机承受扭矩的波动量。 其仪表系数仅为1.5L-1,口径的涡街流量计，其仪表系数更低，仅为约0.2/L-1)，对于这样的流量计，要收集足够多的脉冲数，一要花很长的检定时间，二要有较大的检定设备(较大的标准容器)，由于种种限制。韩国星河SHN-DFC-GCC-U,SHN-DFC-GCC-V,SHN-DFC-GCC-W,SHN-DFC-GCC-X,SHN-DFC-GCC-Y,SHN-DFC-GCC-Z大量库存现货

图2新调节阀特性示意图图3旧调节阀特性示意图由图2，图3中煤气流量变化与调节阀阀位开度的对应关系可以看出，良好状态的调节阀达到了设计使用说明书中的阀位(2%的死区)灵敏度，而性能状态下降的调节阀出现死区范围增大。 如pH值的存在范围，污水的流量大小，加入中和***的品质，中和速度等，通常工厂的生产工艺相对较为，污水的pH值和流量基本，即使有些变化，只要控制参数设置合理一般不会有太大出入，而其它的影响因数比较容易控制。韩国星河SHN-DFC-GCC-U,SHN-DFC-GCC-V,SHN-DFC-GCC-W,SHN-DFC-GCC-X,SHN-DFC-GCC-Y,SHN-DFC-GCC-Z大量库存现货
